Abstract
A flying saucer type toy is made suitable for indoor use by relying on spin velocity, rather than translational velocity, to effect lift. A flat disc is provided with plural generally spiral through-cuts to define plural spiral blade members therebetween. The center of the disc is raised relative to the rim so that the blade members extend between the planes of the disc center and rim and provide lift when the disc is spun about an axis perpendicular to the disc.
